Septic tank and Sewer odors can be a problem. Roof-top plumbing vents allow pressure to equalize as waste water flows down the drain pipes, without a vent your sinks/tubs/toilets would gurgle and glug. These problems can be caused when the wind currents that are supposed to carry the vent gases up and away sometimes bring the sewer gas down to ground level. This can happen if you have a "temperature inversion" or have down-drafts off of a hill. The problem can be more noticeable during evening or nighttime.

Additives rarely work. I tried some "guaranteed to work" additives for 6 months and it did not solve my septic odor problem. That's why I designed and manufactured the "OdorHog" to use on my own home. IT WORKS AT MY HOUSE! More importantly, IT WORKS FOR OTHERS! If it doesn't work for you, return it for a refund.

The OdorHog is an activated carbon filter that can prevent this problem by removing the offensive odors (Hydrogen Sulfide) as they come out of the vent on the roof. Most homeowners can attach the filter themselves in minutes. They last for years and as an added bonus they can prevent snow and leaves from clogging your vent stack.

Use the OdorHog to eliminate unpleasant odors from house vents. OdorHog even eliminates odors coming from RV holding tank vent pipes as well as marine holding tank vent pipes, and septic pumping vehicles. Large waste water facilities have used the OdorHog to eliminate unwanted hydrogen sulfide odors. Have you ever been asked "How do I get rid of the obnoxious smell that ruined my patio party and prevents my family from enjoying our back yard?"

Important Note: If the homeowner is experiencing an odor that originates from inside the house, the problem is most likely a plumbing problem The OdorHog Vent Pipe Filter will not fix that kind of problem and it may make that problem worse. OdorHogs will only eliminate odors that originate at the plumbing vent stack on the roof.
